A civil rights lawsuit has been filed against a Lansing, Ill., police officer who was caught on video threatening a young black teen and holding him pinned on the ground back in June, just because the boy was on his property.

The lawsuit, which was filed Thursday in federal court in Chicago, alleges that Jordan Brunson, 15, was attacked by off-duty Police Officer William Mason even though Jordan never posed a threat. The village of Lansing is also named as a defendant in the suit, the Associated Press reports.

Back in June, the video surfaced showing the officer pinning Jordan down to the grass using his knee, with his hand on the boy’s neck as the distressed teenager pleaded to be released.

“You guys are on my fucking property!” Mason could be heard saying in the widely viewed Facebook video. “I could fucking kill you.”

Jordan said that he was trying to help a friend, who was sitting on the officer’s porch because the other boy had been beaten up pretty badly in a fight.
